I am trying to build a *quiet/silent*, but yet powerful system (i7 2600K) in a relatively compact package (mATX/mini-tower). I am in the US. While I've replaced most components in a computer over the years, this will be my first "from scratch built"

I am not a gamer, so the purpose of the system is to mostly run number crunching programs (most of them under a VM) in additition to doing the usual PC work under Win7 (MS Office/Web stuff) and some development work.

Based on online research I have the following items in mind for a quiet/silent system:

(or would the SeaSonic X Series X650 suffice assuming it's just as good?)

Video card: ??? Again, not a gamer, I was thinking perhaps something fanless, however I don't want to end up with a slouch of a video card that'll sit on top of a powerfull system if I should decide to do some visualizations or check out a game. A friend suggested this card:

Is this a quiet card? Are there other alternatives I should consider? (NVIDIA because I'm interested in CUDA). I currently have 2 identical monitors running at 1280 x 1024 .. hope to move to larger monitors and resolution down the line

Recommendation for quiet fast 1TB HDD?

I hope this configuration makes some sense for a quiet/silent type system, if anyone sees a major mistake here, I would appreciate a heads-up.

Thank you very much for your comments/suggestions.

ps: What is the consensus on getting an SSD for installing the OS (Win 7) and some more frequently used program (like MS Office, and the Oracle Virtualbox VM software (not that big), Chrome browser, and my tiny Windows version of Emacs) .. do you think that would fit on 60 GB and noticably speed up booting and starting programs?

Just do it. You won't be able to go back. Get a 120G SSD and use 60G of it for over provisioning and the other 60G for you OS and applications.

Why do you need the compact package? (Larger and heavier cases usually help stop more noise.)

The first thing you should think about is your workload. I expect that you need more IO Ops then you need graphics power. You should avoid a graphics card, and use that money to get an SSD.

The second thing to decide is how quiet your system really needs to be. Giving up 20% of your speed can cut your noise and your total price by a lot.

CPU: i7 2600K

The "K" over-clocking processors have some of the vitalization features disabled. The "K" series lacks VT-d and TXT features.

They also have double the integrated graphics execution units of the non-"K" processors. This leads to about 40% better performance.

(or would the SeaSonic X Series X650 suffice assuming it's just as good?)

Water cooling usually leads to more noise then air cooling. This is because you have to cool the water with a fan, and you still have move the water with a pump. More components that move means more possible sources of noise.

If you have a full-width case, you should be able to fit any number of 120mm-fan-based coolers. I like the Xigmatek Gaia or the Noctura NH-C12P or C14, but there are many that are cheap and quiet.

It is trendy to get a fan-less, or one of these semi-fan-less (fan on demand?) power supplies. I would save $50 and get a re-badged Seasonic from a distributor like Corsair or XFX. See the power supply reviews at hardwaresecrets.com to find a cheaper unit.

While others want the power supply to have its own intake/output of case air, I view the power supply at a big part of ventilating the case. A good power supply usually comes with a well-controlled high-powered fan.

No video card = No video card noise

You should use integrated graphics. If you do not have a current use for CUDA, you could just buy a card when you really need one.

Are these CRT or LCD monitors? (Dual analog monitors will not work with integrated.)

Many motherboards have dual graphics out for the integrated graphics. They usually have a HDMI and a DVI. You should be able to get adapter cables for any digital monitors.

If you are willing to play your games at 720p or 1024x768, you can play some games on the integrated graphics.

Get a "Green/Eco" drive to have it be quiet. I like Samsung and Western Digital drives for my computers.

From experience, I can tell you that you will want 128 GB or more to run windows and your programs without constant work. Using a 64 GB or smaller SSD means that you are always looking at the drive status and cleaning up files.

The SSD will outlast any component in your system. Devote a lot of your money to the SSD. I would get an Intel 320 300GB version for $550. It is not the fastest, but it will have a 5-year+ lifespan, no matter what you throw at it.

If out cut out the video card, and cut down the power supply. You can save $170 to buy a bigger SSD.

Double check to make sure that CPU: i7 2600K runs VM. I seem to recollect that the K series does not.

Hi,

I am a bit confused by this comment, perhaps we are referring to different things?

I am talking about a Virtual Machine that emulates another OS under the host OS (in this case my Windows 7 install). I have used the Oracle (formerly Sun) VirtualBox software (http://www.virtualbox.org/) w/o problems under a variety of systems, it seems if the host OS system can run, then this software should work too. Am I missing something here or are we talking about different things?

Hi again,

re the VM issue you raised, I did a google search and I see what you are referring to, thanks for pointing that out, I totally hadn't heard of this and I will look into it. Not quite 100% of the implications for me/my work if I would run a Linux guest OS under a 64bit Win 7 (host) installation.

wow .. another behemoth .. how do the motherboards/components cope with all these heavy things hanging off sideways .. it would be one thing if the motherboards were mounted horizontally like in the old typical desktop cases, but vertically in towers, I'd worry about stuff falling off or breaking?

Two reasons, one practical (I have moved a lot, smaller is nicer) and one aesthetic, I don't want to have a huge box dominate my room (goes against my minimalist tendencies :)

Yes, I have to thank ces above, and you for making me aware of this. I didn't know that, and I have been reading about this this evening. I'm not quite sure how important this will be with regard to Oracle's VirtualBox VM software, so now I am not sure if the 2600K is necessarily a better choice than the 2600 and I may go with the 2600 instead.

I may have this wrong, but I thought the K processor had the more advanced HD 3000 integrated graphics vs HD 2000 on the non-K CPU?

Thanks for your comments re cooling and the specific recommendations for the fans in lieu of the H60, I will look into this.

Dr. Jim Pomatter wrote:

Can't argue with that line of reasoning :-) ... but that would require my using a different motherboard, ie one with the H67 chipset correct? Or use a board with the Z68 (??) chipset? I see more for me to investigate.

Yes, I can see that as a good approach, if I am unhappy with the performance of the graphics, I can always spring for a dedicated card later.

Dr. Jim Pomatter wrote:

At this point two identical 19" Dell LCD (both capable of VGA and DVI inputs).

Thanks for the recommendation re the HDD, I plan to use it as storage for data, while I definitely will get a SSD to install my OS and frequently used programs, probably in the 100GB region.

I really appreciate you having taken the time to give me such detailed and informative feedback.

Yes, the Intel HD 2000 has 6 execution units and the Intel HD 3000 has 12 execution units. As the bandwidth available has not changed, the performance only improves by 30-70%.

If you are worried about the weight of heatsinks (or want to save money), you can get the Xigmatek Loki. It is a 92mm cooler, so it is smaller then the 120mm coolers. Reviews claim that it is just as quiet as the 120mm coolers, so it saves you money and space without adding noise.

The Loki only weights 330 grams. This is under the Intel recommended limit of 450 grams. Any heatsink that weights over 450 grams should be removed from the computer before you ship the computer.

You should get the Z68 or the H67 so you can use the graphics. You will need a DVI-to-HDMI cable if you want to use both monitors. (I assume that you have a DVI-to-DVI cable.)

Noctua also has a nice 92mm tower. I believe it is a bit better but it does cost more.

Thanks .. right now I'm stuck on the 2600 w/ VT-d and the 2600K w/o VT-d issue/decision :-) ... and whether this would even matter. Plus I am not sure many motherboards/BIOS/Chipsets(??) support this feature yet .. at least the original mATX ASUS motherboard I was hoping to get doesn't mention it in its manual.

Re the CPU cooler, I suppose I could see how the stock fan does and if it's too noisy replace it with one of the suggestion I have gotten here.

More great advice

Thanks .. I've noted all.

Once I figure out the 2600 vs 2600K issue (and what motherboards support VT-d, and whether this would really matter in terms of performance) I'll go on a spending spree - but it seems I have some more research left to do before then.

Compared to the i5-2500, the i5-2405S uses 30 fewer watts (65 watts rather then 95 watts). It is also about 600 mhz slower. It also does not have VT-d or VT-TXT tech. These virtualization instructions are only used by servers, and Intel does not want low-watt desktop chips to hurt its server-chip sales.
